Who is Tim Ryan's direct competition for the nomination?

From a recurring series of national surveys INSIDER conducts, we can determine which other candidates Tim Ryan is competing with and how he matches up in the large Democratic field of candidates.

Former Vice President Joe Biden: Biden and Ryan have considerable similarities on policy, so it is no surprise that 64% of Ryan's supporters would also be comfortable with the Scranton, Pennsylvania native as the nominee. This also provides Ryan with a prime opportunity to get ahead in the race if Biden's campaign flounders.

Sen. Cory Booker: According to our polling, 50% of Ryan's supporters would also be satisfied with Booker as the Democratic nominee. Both candidates have a working class background, legal careers, and many years as legislators.

Sen. Kamala Harris: Ryan also garners similar support among Harris backers. As much as 49% of Ryan's supporters would also like Harris as the Democratic nominee.

INSIDER has been conducting a recurring poll through SurveyMonkey Audience on a national sample to find out how different candidate's constituencies overlap. We ask people whether they are familiar with a candidate, whether they would be satisfied or unsatisfied with that candidate as nominee, and sometimes we also ask whether they think that person would win or lose in a general election against President Donald Trump.

Ryan has also called for lowering the corporate tax rate from its previous rate of 35% (it is now 21% since the new tax law took effect).

What are Tim Ryan's political successes?

Ryan has served on the House Appropriations Committee, securing grant funds for protecting pregnant women at risk of abuse as well as rebuilding an Ohio fire department, according to the Cleveland Plain Dealer.

"Whether it is securing facility and equipment upgrades for our active duty servicemembers, implementing better care for our veterans, increasing resources to combat the opioid epidemic, strengthening retirement security, combating wage stagnation, boosting American manufacturing, or providing funding for local transportation projects in the state of Ohio - Congressman Ryan has fought and will always continue to fight for the American people," said Ryan's spokesman, Michael Zetts.

How much money has Tim Ryan raised?

Could Tim Ryan beat President Trump?

According to polling from INSIDER, Ryan currently has a modest level of name recognition, with 22% of likely Democratic primary voters having heard of him. Of that group, 12% think Ryan would beat Trump in a head to head matchup, but just 9% think he would lose to the incumbent Republican.

Like many in the Democratic field, Ryan has a lot of ground he needs to gain to become a formidable candidate in the general election as well as the primary.
